extrinsic allergic alveolitis

Extrinsic allergic alveolitis is a lung disorder resulting from repeated inhalation of organic dust, usually in a specific occupational setting.

Chronic human exposure via humidifiers or air conditioners can lead to hypersensitivity pneumonitis (extrinsic allergic alveolitis) or "humidifier lung".

It is classified as a hypersensitivity pneumonitis (also called extrinsic allergic alveolitis)-an inflammation of the alveoli within the lung caused by hypersensitivity to inhaled organic dusts.

Exposure to metalworking fluids can cause; irritation of the skin/dermatitis, occupational asthma, bronchitis, irritation of the upper respiratory tract, breathing difficulties or, rarely, a more serious lung disease called extrinsic allergic alveolitis (EAA), which can cause increasingly severe breathing difficulties in recurrent episodes, following repeated exposure.
